1. INTRODUCTION
Usually, a wrist watch can be used for watching or observing
time along with alarm settings or some familiar functions in
day-to- day life. But apart from this, it can be used as a cell
phone having the facilities of calling, message transmission
and receiving, voice and video recording, FM and AM radio ,
photo capturing. It also has memory card slots along with sim
card slots. It can also be used as for playing different types of
games. It will also have internet connectivity. Apart from the
cell phone extension, the same wrist watch can also be used as
medical testing equipment. It can be used for testing diabetes,
blood pressure, tuberculosis, Rh factor, RBC count, WBC
count, plasma count, hemoglobin count and all the blood-
related diseases or the blood related queries like the blood
group of a person. It also acts as a running pedometer. It can
also help in controlling blood pressure. It can also be used as
BMI calculator, BMR calculator, body fat calculator, activity
calculator, calorie calculator.
2. LITERATIVE STUDY
By looking into the various concepts, materials and othealike
things or rather records in internet and the books available to
us, it has been found where it is clearly stated that already the
kinds of wrist watches havin all the functions of the cellphone
that we have discussed in the previous section of our discussion
has been clearly and successfully incorpated in this real world.
The Wrist watch with embedded mobile applications can be
categorized into three categories, on the basis of a close
observation or study. The three categories are briefly described
below and the three categories are-
A. Wrist watch with keypad
FIG 1: WRIST WATCH WITH KEYPAD
This is a type of wrist watch with keypad which is having the
keypad in the screen itself. This model is little outdated. An
image of it is clearly displayed in figure 1. It is unable to
display time. Though it appears as a screen touch cell phone
but it is not. It has only three functions making a call, receiving
a call, message transmission and receiving and setting alarm.

The above figure clearly depicts a wrist watch which is having
keypad installed in it. Unlikely the previous model described
above (figure 1), which is having its keypad in the screen; the
new model is having the keypad on the strip (wrist watch belt)
of the wrist watch. If we see it clearly one can also depict that it
is having a camera with a standard rating of 2 megapixels. It
has also a microphone in it which will help to capture the voice
of the user and will be helpful in transmitting it.
It is the simplest types of wrist watch having an embedded cell
phone in it. It simply has the function of making a call,
receiving a call, image capturing, FM radio, playing game,
voice recording, timer, calculator, saving notes, memorandum,
message transmission and receiving, setting alarm and the alike
things. It does not have memory card slots or it have media
player or video player. It does not have any wifi connectivity or
Bluetooth or infrared connection. It only have image viewer,
where we can zoom the image, edit the image and do all kinds
of image related operations.
B. Wrist watch having smart applications
This is a type of wrist watch in which keypads are not present.
An image of it is displayed in figure 3. In this type of model, in
the strip (belt) of the wrist watch, there is just a call (green
button) and a call end (red button). It has a joystick in the side
which toggles between the options and the both button in
which dot (.) is present (as shown in the figure) near both call
and call end buttons gives the option to open, go back read,
write message and all the alike things available. The options
available will be displayed on the screen and after watching or
observing the screen only, one can know what action should be
taken or which button out of this two buttons should be
pressed. It can also display time (analogue clock) on the wrist
watch.
Fig 3: Wrist watch having smart application
It is the type of wrist watch having an embedded cell phone
having smart applications in it. It has the function of making a
call, receiving a call, playing game, calculator, saving notes,
memorandum, message transmission and receiving, FM radio,
timer control, image capturing, video recording, voice
recording, song recording, setting alarm. It also has packet data
connection, Bluetooth and also infrared connection (in some
models). Till now only 2G connection can be incorporated in
this type of model, 3G or 4G connection is till now, but in the
near future, 3G or 4G is expected to make an impact in near
future. For the concern in terms of economic feasibility,
laymen can afford it i.e. it is economically feasible to common
people. It has also games which even has java games in some
models. It has memory slots (microsd) expandable till 8 GB
(till date). It is also having a sim card slot having the facility of
a single sim only.
C. Wrist watch having android applications
It is a type of wrist watch in which keypads are also not
present. It is purely screen touch with android applications
incorporated in it. The image of it is displayed in figure 4. It is
having touch digi pen in it. It also does not have any buttons
present anywhere on the wrist watch (whether it be on the
strips of the wrist watch or in and around the wrist watch). It
also can display time (analogue as well as digital clock) on the
wrist watch.
Fig 4: Wrist watch having android application
It is the type of wrist watch having an embedded cell phone
having smart applications in it. It has the function of making a
call, receiving a call, playing game, calculator, saving notes,
memorandum, message transmission and receiving, FM radio,
timer control, image capturing, video recording, voice
recording, song recording, setting alarm. It also has packet data
connection, Bluetooth and also infrared connection. It also has

wifi connection facility in it. It also has java enabled game
loaded in it. It has memory card slot (microSD) expandable up
to 32 GB. It also has a memory card slot having the facility of
inserting two Sims at the same time (dual sim). It also has GPS
connectivity in it in which we can trace where we are at the
moment, what are the hotels, entertaining places, cinema halls,
shopping malls near or local to that place. It also gives a
satellite image of the whole area (terrain). It also has the
facility of providing navigation to a place in satellite images. It
also has radio connectivity which has both FM and AM
facilities. It has file reading options. It can display file in pdf
format and also word format. One can edit the document and
can also zoom, copy and paste anything on the document.
Besides all this, this type of wrist watch also has smart voice
detection in which if the user speaks something or rather orders
anything, immediately the smart phone will search or do
anything to give a required action to the order given by the
user.
D. Comparision between all the three types of wrist
watches
By observing the comparison one could figure it out in which
respect which one of is better and according to it one could
make a choice which one is more preferable to them in their
own terms of consideration.

3. EXISTING METHODOLOGY
There is already an existing model which will be described in
this section. Along with it, some new concepts will be
described or explained briefly so that one can fully understand
the new concept or the idea fully.
Fig 5: Backside view
The backside view (dissected image) can be seen where the
battery (Lithium Ion) has been removed. As a result, memory
card slots along with the memory card slots. In figure 5, which
will display a more magnified detailed image of the backside
view the battery along with the type of memory card inserted in
it is clearly shown.
Fig 6: Backside view
The wrist watch can also be connected to a laptop/computer via
Bluetooth connection as well as through usb connectivity. It
also has a power button to switch it on or off (figure 7).
Fig 7: Side view
The menu button is also clearly visible in which the menu
opens up in the screen and the user can do the required
operations that the user wishes to do it.

Also there is a camera which can be clearly visible in the figure
8. In the existing model, only the camera can capture photos,
videos and display it in the image viewer and the video player
etc. A wrist watch with the image present in the image viewer
can look like as shown clearly on the figure 9.
Fig 8: Camera in wrist watch
Fig 9: Image in image viewer
There is a common doubt arising in everyone’s mind as to how
to insert the sim card and the memory card in the sim card slots
and the memory card slots respectively. The sim card is the
normal sim card commonly used in our day-to-day life It would
be rather clear or clarified be in the Figure 10, where it is
shown that when and where and how the sim card is inserted.
In the same way, the memory card is inserted in the memory
card slot on the opposite side of the side where the sim card
was been inserted.
Fig 10: Sim card and its slot
4. PROPOSED METHODOLOGY
In Figure 8, the camera is visible; it can be further used as a
projector. The LED that is present in the camera can emit the
light of an entire document on a nearby surface and as it can
emit the document; obviously the image will be magnified.
Thus, it will help any person to refer the document on-the-go.
In this way, it could act as a great help to mankind as human
eye could also don’t have to concentrate heavily on the
document.
Coming to the medicinal and health concept, in the strip (as in
Figure 11) of the wrist watch, there can be small test tubes
(ignition tube as in Figure 12) attached in the strip of the wrist
watch. The wrist watch strip attached in hand will have a small
or needle attached with it, which is inside the wrist watch,
which when given the option the needle gets out and pierces a
little in the body and the blood can then be transferred to a test
tube. In this way, the blood could be collected. This sample so
collected on the ignition tubes can be extracted later on and as
such it could be further send to any laboratory or blood
diagnostic centre by which blood group, Rh factor, RBC count,
WBC count, Plasma count etc. and all the blood related queries
and the diagnostics can be performed.

Fig 12: Ignition tube
It can also act as pedometer. The wrist watch has an application
through which it regularly checks the amount of sweat that is in
touch of the strip and it can calculate and make a conclusion
what is the amount of time that the user or the person should
walk or run. The same application can be used to control blood
pressure. If there is extraordinary sweat emerging in
extraordinary time of the day, then a vibration will be
encountered, which will not stop automatically. It will alert the
user or the person that something regarding the Blood Pressure
is wrong and that person can act accordingly in the required
appropriate time.
The wrist watch can also be used as for analyzing the diabetes
or the sugar level. It can use the concept of “Accu-chek
glucometer” for monitoring the level of sugar or the diabetes
level. The original Accu-chek is generally large in shape, so
accu-chek cannot be directly used here since, it will not be
feasible with it. So, the software used inside the device Accu-
chek is used. The figure of the device accu-chek is in Figure
13.
Fig 13: Accu-chek
It can also be used for many health-related queries. It can be
used for calculating Body Mass Index (BMI). The height and
weight of the person is asked. There is fields in which a person
can enter and by clicking on calculate the software will be able
to calculate. A format of BMI calculator is in Figure 14.
Fig 14: BMI calculator
It can be also used for calculating Basal Metabolic Rate
(BMR). The required fields to be entered are both different for
male and female since the body requirements are different for
both male and female. BMR calculator for both the types are in
Figure 15.
Fig 15: BMR calculator
It can be also used for calculating Body Fat Calculator. The
required fields to be entered are both different for male and
female since the body requirements are different for both male
and female. Body fat calculator for both the types is in Figure
16 and Figure 17.

Fig 17: Body fat calculator (for male)
It can be used for calculating activity calculator. There is fields
in which a person can enter and by clicking on calculate the
software will be able to calculate. A format of activity
calculator is in Figure 18.
Fig 18: Activity calculator
It can be used for calculating calorie. There are fields in which
a person can enter and by clicking on calculate the software
will be able to calculate. A format of calorie calculator is in
Figure 19.

CONCLUSIONS
So, in this discussion we can conclude by saying that wrist
watch can be used as a mobile with many features (with almost
all the functions). Furthers the concepts or the ideas that can be
incorporated on the wrist watch can be extended and can be
implemented keeping in consideration the view of economic
and technical feasibility.
